Best Video Converter

Get converted MP4 files ready to post, without touching a single slider. Upload your video files (AVI, MOV, MKV, WebM, up to 500MB), say something like "conv...

Security Scan

The skill's declared requirements and runtime instructions line up with a cloud video-conversion service and don't ask for unrelated system access, but the publisher is unknown so verify the external service before use.

Purpose & Capability

The skill is a cloud-based video converter and the SKILL.md directs the agent to a nemovideo.ai API, requests a service token (NEMO_TOKEN), session management, upload and render endpoints — all consistent with the described purpose.

Instruction Scope

Runtime instructions stay focused on authentication, session creation, file upload, SSE handling and render polling. Minor inconsistencies: metadata lists a config path (~/.config/nemovideo/) and asks to auto-detect an install path for X-Skill-Platform, but the document does not clearly explain what (if anything) should be read from that config path. The skill also instructs generating an anonymous token via the service if NEMO_TOKEN is not set, which is expected for this workflow.

Install Mechanism

Instruction-only skill with no install spec and no code files — lowest-risk install surface. Nothing is downloaded or written by an install step.

Credentials

Only one env var is required (NEMO_TOKEN), which matches the service authentication need. The declared configPaths entry is not justified in the instructions; confirm whether the skill will read user config under ~/.config/nemovideo/ before installing.

Persistence & Privilege

The skill is not set to always:true and does not request system-wide changes. It uses per-session tokens and session IDs; nothing indicates it will modify other skills or agent-wide settings.

Assessment

This skill appears coherent for a cloud-based video-conversion service. Before installing: (1) confirm you trust the external domain (mega-api-prod.nemovideo.ai) and understand their privacy policy — you will be uploading videos; (2) only provide a NEMO_TOKEN issued by that service (do not point it at unrelated secrets); (3) ask the publisher whether the skill will read ~/.config/nemovideo/ or other local files (metadata lists that path but the instructions don't explain why); (4) avoid uploading sensitive or private videos until you verify storage/retention practices and whether the service keeps copies; (5) prefer creating an account with the service rather than using long-lived tokens you reuse elsewhere. If you want higher assurance, request a publisher/homepage or source code for review before enabling the skill.

Getting Started

Share your video files and I'll get started on AI format conversion. Or just tell me what you're thinking.

Try saying:

• "convert my video files"
• "export 1080p MP4"
• "convert this AVI to MP4 at"

Automatic Setup

On first interaction, connect to the processing API before doing anything else. Show a brief status like "Setting things up...".

Token: If NEMO_TOKEN environment variable is already set, use it and skip to Session below.

Free token: Generate a UUID as client identifier, then POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id: <uuid>. The response field data.token becomes your NEMO_TOKEN (100 credits, 7-day expiry).

Session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Save session_id from the response.

Confirm to the user you're connected and ready. Don't print tokens or raw JSON.

Best Video Converter — Convert Any Video to MP4

Drop your video files in the chat and tell me what you need. I'll handle the AI format conversion on cloud GPUs — you don't need anything installed locally.

Here's a typical use: you send a a 3-minute AVI file from an old camcorder, ask for convert this AVI to MP4 at 1080p, and about 20-40 seconds later you've got a MP4 file ready to download. The whole thing runs at 1080p by default.

One thing worth knowing — shorter clips convert faster — split long videos before uploading if you are in a hurry.

Matching Input to Actions

User prompts referencing best video converter, aspect ratio, text overlays, or audio tracks get routed to the corresponding action via keyword and intent classification.

User says...	Action	Skip SSE?
"export" / "导出" / "download" / "send me the video"	→ §3.5 Export	✅
"credits" / "积分" / "balance" / "余额"	→ §3.3 Credits	✅
"status" / "状态" / "show tracks"	→ §3.4 State	✅
"upload" / "上传" / user sends file	→ §3.2 Upload	✅
Everything else (generate, edit, add BGM…)	→ §3.1 SSE	❌

Cloud Render Pipeline Details

Each export job queues on a cloud GPU node that composites video layers, applies platform-spec compression (H.264, up to 1080x1920), and returns a download URL within 30-90 seconds. The session token carries render job IDs, so closing the tab before completion orphans the job.

Base URL: https://mega-api-prod.nemovideo.ai

Endpoint	Method	Purpose
/api/tasks/me/with-session/nemo_agent	POST	Start a new editing session. Body: {"task_name":"project","language":"<lang>"}. Returns session_id.
/run_sse	POST	Send a user message. Body includes app_name, session_id, new_message. Stream response with Accept: text/event-stream. Timeout: 15 min.
/api/upload-video/nemo_agent/me/<sid>	POST	Upload a file (multipart) or URL.
/api/credits/balance/simple	GET	Check remaining credits (available, frozen, total).
/api/state/nemo_agent/me/<sid>/latest	GET	Fetch current timeline state (draft, video_infos, generated_media).
/api/render/proxy/lambda	POST	Start export. Body: {"id":"render_<ts>","sessionId":"<sid>","draft":<json>,"output":{"format":"mp4","quality":"high"}}. Poll status every 30s.

Accepted file types: mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac.

Three attribution headers are required on every request and must match this file's frontmatter:

Header	Value
X-Skill-Source	best-video-converter
X-Skill-Version	frontmatter version
X-Skill-Platform	auto-detect: clawhub / cursor / unknown from install path

All requests must include: Authorization: Bearer <NEMO_TOKEN>, X-Skill-Source, X-Skill-Version, X-Skill-Platform. Missing attribution headers will cause export to fail with 402.

Error Handling

Code	Meaning	Action
0	Success	Continue
1001	Bad/expired token	Re-auth via anonymous-token (tokens expire after 7 days)
1002	Session not found	New session §3.0
2001	No credits	Anonymous: show registration URL with ?bind=<id> (get <id> from create-session or state response when needed). Registered: "Top up credits in your account"
4001	Unsupported file	Show supported formats
4002	File too large	Suggest compress/trim
400	Missing X-Client-Id	Generate Client-Id and retry (see §1)
402	Free plan export blocked	Subscription tier issue, NOT credits. "Register or upgrade your plan to unlock export."
429	Rate limit (1 token/client/7 days)	Retry in 30s once

SSE Event Handling

Event	Action
Text response	Apply GUI translation (§4), present to user
Tool call/result	Process internally, don't forward
heartbeat / empty data:	Keep waiting. Every 2 min: "⏳ Still working..."
Stream closes	Process final response

~30% of editing operations return no text in the SSE stream. When this happens: poll session state to verify the edit was applied, then summarize changes to the user.

Translating GUI Instructions

The backend responds as if there's a visual interface. Map its instructions to API calls:

• "click" or "点击" → execute the action via the relevant endpoint
• "open" or "打开" → query session state to get the data
• "drag/drop" or "拖拽" → send the edit command through SSE
• "preview in timeline" → show a text summary of current tracks
• "Export" or "导出" → run the export workflow

Draft field mapping: t=tracks, tt=track type (0=video, 1=audio, 7=text), sg=segments, d=duration(ms), m=metadata.

Timeline (3 tracks): 1. Video: city timelapse (0-10s) 2. BGM: Lo-fi (0-10s, 35%) 3. Title: "Urban Dreams" (0-3s)

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "convert this AVI to MP4 at 1080p" — concrete instructions get better results.

Max file size is 500MB. Stick to AVI, MOV, MKV, WebM for the smoothest experience.

Export as MP4 for widest compatibility across devices and platforms.

Common Workflows

Quick edit: Upload → "convert this AVI to MP4 at 1080p" → Download MP4. Takes 20-40 seconds for a 30-second clip.

Batch style: Upload multiple files in one session. Process them one by one with different instructions. Each gets its own render.

Iterative: Start with a rough cut, preview the result, then refine. The session keeps your timeline state so you can keep tweaking.
